I installed the Propulsion theme today and everything was working fine until I activated the Woo-Commerce plug-in. Once I activated the plug-in, the following error appeared at top of my word press dashboard page

Warning: session_start() [function.session-start]: open(/var/chroot/home/content/49/8970949/tmp/sess_ngk7apo5rl5du5sh39bjigd1j1, O_RDWR) failed: No such file or directory (2) in /home/content/49/8970949/html/wp-content/plugins/woocommerce/woocommerce.php on line 80

also, at the bottom of the page, the next line showed up

Warning: Unknown: open(/var/chroot/home/content/49/8970949/tmp/sess_ngk7apo5rl5du5sh39bjigd1j1, O_RDWR) failed: No such file or directory (2) in Unknown on line 0

Also, my webpage doesn’t display the propulsion theme, instead it only shows the same error messages (at least I think they are the same).
